产品详情/ Product details
SF6 Dew point and pressure temperature transmitter (WFS– S6DPT) adopts new material polymer film sensor technology, which has the advantages of high humidity response of general polymer film sensors, and has superior low humidity measurement response level. The sensor circuit design can automatically compensate for drift caused by temperature, pollution, and aging, ensuring long-term reliable and high-precision measurement. Combined with the high stability of the new material polymer film sensor technology, the recalibration cycle is extended to more than two years. The innovative temperature compensation algorithm and multi-point temperature compensation check before delivery greatly improve the temperature drift of the sensor and ensure high precision measurement in a wide temperature range.
